DEVICE F03 CARBURETING AIR.

Be it known that I, GASTON PAUL JEAN LION, a citizenfof the French Republic, and

resident of Levallois-Perret, Seine, France, have invented certain new and useful Improvements in"` Devices for Carbureting Air with Crude Naphthalene, of which the following is a speciiication.

The present invention relates to, a device by means of which crude naphthalene may be used'for carbureting the air of explosion motors. It is a well known facttthat such crude naphthalene cannot be used in motors because of the deposit of impurities contained in said crude materiah The improvement consists in that the crude naphthalene is melted at a moderate temperature in a common or main tank,

this melting being produced by the exhaust gases of thevmotor. Said main tank feeds a smaller-fone, which is a float chamber, said oat chamber beingdisposed in such a mannerthat it can be heated to the boiling-teur. perature of the naphthalene. The float chamber is connected with a third chamber from which air carbureted with naphthaa lis the supply-tank of preferably rec,

tangular shape, the longer wall of which is provided witha lateral chamber?) forming' a heating acket through which flow the eX- `Ahaust gases of the motor for producing the preliminary melting of the crude naphthalene. The supply tank a is connected with the float chamber c by means of a tube al. Thefloat c1 of this second tank or chamber works on a valve e2 which controls theA connecting4 oluctv al. The float chamber c isprefe'rablv integral wit-hithe supply tank c so that itis adjacent to the heating jacket b, the adjacent. surfacevbeing large enough for maintaining the melting temperature of the, naphthalene Vin said iioat chamber e.

Said oat Chamber e, is connected with a carburetingchamber f and 'consequently the Specication of Letters Patent. Application mea March 16, 1912. serial No. 684,234.

level of the liquid in the latteris the same i as in the float chamber. Said chamber f is also provided with- 'a heating jacket g which surrounds a part of the carbureting chamber f and into which part' of the eX- haust gases enter through g1 and escape through g2. A second jacket #surrounds the first one g and servesfor heating air drawn through the suction valves 7c3 and which flows from the jacket through the tube 7c and bubbles through the strongly heated `crude naphthalene mass in the chamber f, said air entering the. naphthalene through downwardly directedl ports of a ring k2 and leaving the tank f through the tube k1.

The top ofv the carbureting chamber is tightly closedby means of a cover Z thro-ugh which extends the depending pipe c and the outlet pipe k1. At its lower end it is provided with an exhaust cock g for evacuating the precipitates or deposited. impurities from the naphthalene.

. Within thenaphthalene mass is provide an absolutely tight hollow body m which is connected by means of a capillary tube 'fz' The exhaust pipingo ofi the motor is con-l Patented June 24, 1913.

nected with a valve casing u in which a distributing flap valve u1 is movable. According to the position of thevalve u1, it will permit the eXhaust gases to pass through g1 to the heating jacket g of the chamber f (from which they flow through the tube g2 to theA heating jacket or permit a part or the whole of said gasesto jacket b.

In the hot air inlet pipe ciland outlet pipe k1 of the chamber f are inserted cocks M 'r1 respectively and betweenv the pipes 7c and k1 is inserted a connection having athird cock r2, so that it is -made possible to draw carburetedhot airuo'r napvhthalene vaporsv phragm which bears against one fend of a rod p2 provided with a spring p3 and guided in a stirrup p4, said rod 722, by meansy ofthe connecting lever 725, regulating.'thefdistribpass directthrough the pipe t to said" uting valve u1 according to the temperature of the tank i, f

The device works as follows: When the motor is started by means of usual fuel (such as gas; kerosene, benzin or the like) and has worked forl a few minutes, the eX-' haust gasesfrom 'oare conveyed through the heating jacketg of the'chamber f and then through the heating jacket b of the tank a and float chamber e, (while the valve u1 isin the position shown in dotted lines) so that after a time the naphthalene will boil r in f and will-,melt in a and e. It is to be noted that the same heating jacket serves at one and the same time for both -tank a and chamber e, due to the location of the respective parts. Meanwhile the temperature regulating device controlled by the body m has rotated the valve u1 to the posi- 'tion shownA in full `lines and which corresponds to 'the desired temperature which must be kept in the tank, said valve correspondingly throttling the flowing of the exhaust gases. This is obtained by the expansion of the air contained in the body m which presses the diaphragm p1 outward andl consequently moves the valve u1 by means of the rod p2 and the lever p5. It will be understood'that the crude naphthalene in the chamber f may-bemaintained at a desired degree of heat by correspondingly adjusting the tension of the regulating spring p3 of the diaphragm. v

During the operation described the cocks 1 and r1 are kept closed, and the cock r2 open, so that the motorfby means of suction valves 7c3, draws some strongly heated air through the air acket L, pipe c, cock r2 and pipe k1. It will be understood that the pipe k1, Which cannot be heated by conduction, is heated by the air drawn in to such a degree that the naphthalene may flow-through it without any danger of said tube being obstructed by the solidication of thenaphthalene. Now the motor can be fed with naphthalene in two ways, by sucking air which 1s oversaturated with naphthalene\ vapors in the chamber f or by sucking naphthalene vapors only:

First case: Air saturated with naphthatene vapors-The motor` duct for the feeding of gas, benzin or the likev is closed and immediately the cocks 7 and r1 are opened and the cock r2 is closed. The motor draws by suction through the pipe k1 above the naphthalene of the tank f. Hot air proce'eding from the jacket it enters through the pipe k and bubbles through the naphthalene lfrom the perforated ring 7a2. By virtue of this bubbling action, only the most volatile naphthalene va ors are forced to the motor,

while the heavier oils, which constitute the impurities of the crude naphthalene, remain within the chamber The mixture of naphthalene and air is finally added to the fresh air which is provided by the usual carbureter (without carbureting vapors) for providing the explosive mixture.

Qa? case: Naphthalem vapors only/. The

process is the same but the cock 1' is closed..

The air does not enter through the ring c, but the suction which is produced above the naphthalene at f will drawi the desired` ,independent of the' car ureting chamber jacket for direct communicationfromy said exhaust pipe. to the jacket of the supply tank.

2. In a device for carbureting air with crude naphthalene vapors, the combination, v with a ,supply tank and a carburetingchamber communicating therewith, of'a heating jacket for the supplytank, a heatlng jacket surrounding and extending 'longitudinally of. the carbureting chamber, an engine exhaust pipe communicating with thelower portion of the carbureting chamber jacket, a pipe affording communication between an upper portion ofthe carbureting chamber jacket and an upper portion of thejjacket,y

for the supply tank, and means of direct communication betweenA the exhaust pipe and the upper portion of Vthe jacket for the supply tank.v l

4. In a device of the class described, the.

combination, with la carhureting chamber and means for supplying naphthalene there? to, of a heating jacket surrounding the `carbureting chamber, a hot air jacket surrounding the heating' jacket, a tube leading from r I the hot air jacket to within the carbureting chamber and extending'below the naphtha- Y lene level therein, a distributing tube leading from the carbureting chamber from' a point above the naphthalene level therein, a by-pass aTording direct communication between the air supply pipe and the distributing pipe, and valves for the by-pass and pipes for enabling the delivery through said supply pipe of hot air, earbureted air, or pure naphthalene vapors.
